Target RA (J2000): 76.7312088012695 and deg Target Dec (J2000): 10.9980697631836 and deg Gaia GMag: 9.68 Programme ID: CH_PR140069 Programme Manager: SZABO PI of observing programme: Benz Title of programme: Axis 3 - Photometric Transients in Dusty Debris Disks Abstract: We observe systems with warm dust disks regardless to the orientation of the disk but with positive detections of photometric transients from the disk with TESS. The targets will be selected from the results of Ansdell et al 2020 and Gaidos et al. 2022 in respect to the expected efficiency of CHEOPS observations and if possible simultaneously to TESS observations. The simultaneous CHEOPS+TESS multiband data will give us the first two-band space photometry of scattering dust in distant solar systems. [truncated! Please see actual data for full text]

目标赤经（J2000坐标系）：76.7312088012695 度；目标赤纬（J2000坐标系）：10.9980697631836 度；盖亚（Gaia）卫星G星等：9.68；项目编号：CH_PR140069；项目主管：SZABO；观测项目首席研究员（Principal Investigator）：Benz；项目名称：《轴3——尘埃碎屑盘内的光度瞬变》；摘要：本研究针对拥有暖尘埃盘的天体系统开展观测，不限制盘体朝向，但需通过TESS（Transiting Exoplanet Survey Satellite，凌日系外行星巡天卫星）成功探测到该尘埃盘的光度瞬变信号。目标天体将从Ansdell等（2020）与Gaidos等（2022）的研究成果中筛选，筛选依据为CHEOPS（Characterising Exoplanet Satellite，系外行星特征卫星）的观测预期效率，且尽可能与TESS观测同步进行。同步获取的CHEOPS+TESS多波段数据，将为遥远太阳系外的散射尘埃提供首组双波段空间测光数据。【文本已截断，请查阅完整原始数据以获取全文】
